GEGN8615 Iss 1

This document contains guidance on the application of the PRM NTSN, particularly when undertaking work that would not necessarily constitute an upgrade, but where there is a reasonable opportunity to move towards partial compliance with the requirements of the NTSN.

The new Guidance Note clarifies the PRM NTSN requirements for rolling stock and infrastructure in a GB context, particularly where a reasonable opportunity exists to improve vehicles and infrastructure, to move them towards compliance with the PRM TSI – even when this is not required under the Railway Interoperability Regulations (RIR) 2011. 
The new guidance is particularly applicable to modifications to existing vehicles and infrastructure, and is intended to assist designers, owners and operators, and approvals bodies in determining the applicable requirements from the PRM NTSN, thus simplifying the design and approvals process.
